Distributed systems (to be exact, distributed computer systems) has come a long way from where it was started. At the very beginning, one computer could only do one particular task at a time. If we need multiple tasks to be done in parallel, we need to have multiple computers running in parallel. But running them parallel was not enough for building a truly distributed system since it requires a mechanism to communicate between different computers (or programs running on these computers). This requirement of exchanging (sharing) data across multiple computers triggered the idea of the message-oriented communication where two computers share data across using a message which wraps the data. There were few other mechanisms like file sharing, database sharing also came into the picture.

WSO2 ESB uses the property mediator to change the behavior of the messages flowing through the ESB mediation engine. HTTP transport level properties mentioned below can be used to access and change the http level properties. You can get a general idea about ESB properties from this blog post. http://soatutorials.blogspot.com/2014/03/wso2-esb-properties-tutorial.html HTTP Transport properties POST_TO_URI This property makes the outgoing URL of the ESB a complete URL. This is important when we talk through a Proxy Server. You can set this property as below. <property name="POST_TO_URI" scope="axis2" value="true"/> Here is an example in which we can use this property. <?xml version="1.0" encoding="UTF-8"?> <proxy xmlns="http://ws.apache.org/ns/synapse"        name="SampleProxy"        transports="https,http"        statistics="disable"        trace...
